I'd like to identify it. It's an oval port intake. Has "Q-Jet" cast in passenger side top toward front & has a spreadbore pattern/carb mount. It has "GM1" with a "T" under it. I think the casting number is "3888948" or "3883948" but a search on this forum makes me think it probably is "3866948". Those "6's", "8's", & "3's" are a little old & hard to distinguish. It also has "D256" cast on the top toward the back between carb mount & the distributor hole.

Thanks in advance for your patience & help.....ODIE

the manifold was used in 1966 67 and 68 and that one looks to be april 25 of 1966 (d256) in 66 it was used on passenger cars and chevelles and the book says that if it was on a chevelle in 1966 it would be an A.I.R (smog) 325hp 396
